Tailor-made X-rays for research and development

Start-up expansion with funding from IFB Hamburg

14-Oct-2021

The high-tech Spin-Off TXproducts, founded in April 2021 on the DESY campus in Hamburg, will receive funding from Investitions- und Förderbank Hamburg (ifb). TX stands for "Tailored X-Ray", and the company develops solutions for customizing synchrotron X-rays beams for experiments at large-scale ...

Localized growth of silicon crystals

Fraunhofer IWM presents the »Triboepitaxy« concept

07-Oct-2021

Four scientists from Freiburg have succeeded for the first time to simulate the localized growth of silicon crystals using shear-induced amorphization and recrystallization. In the future, experts could use this concept to tailor crystalline silicon structures for nanotechnology applications, ...

Artificial opals measure temperature and time

Researchers discover novel sensors

30-Sep-2021

Due to their iridescent colors, opals have been considered particularly precious gemstones since antiquity. The way these stones shimmer is caused by their nanostructures. A research group led by Prof. Dr. Markus Retsch at the University of Bayreuth has produced colloidal crystals mimicking such ...

Tiny porous crystals change the shape of water to speed up chemical reactions

The new approach is poised to play a role in helping chemical manufacturers move away from harmful solvent catalysts in favor of water

22-Sep-2021

Chemical engineers at the University of Illinois Urbana-Champaign now understand how water molecules assemble and change shape in some settings, revealing a new strategy to speed up chemical reactions critical to industry and environmental sustainability. The new approach is poised to play a role ...

Solar cells: Layer of three crystals produces a thousand times more power

The result surprised even the research group

21-Jul-2021

The photovoltaic effect of ferroelectric crystals can be increased by a factor of 1,000 if three different materials are arranged periodically in a lattice. This has been revealed in a study by researchers at Martin Luther University Halle-Wittenberg (MLU). They achieved this by creating ...

Shiny mega-crystals that build themselves

New mega-crystals exhibit unique properties such as superfluorescence and may well usher in a new era in materials science

28-May-2021

An international team led by Empa and ETH Zurich researchers is playing with shape-engineered nanoscale building blocks that are up to 100-times larger than atoms and ions. And although these nano "Lego bricks" interact with each other with forces vastly different and much weaker than those ...

Controllability of ionization energy of atoms promises advancements in chemical synthesis

27-May-2021

Ionization energy is one of the most important physicochemical parameters. It is defined in terms of the amount of energy required to rip an electron from an atom. The dependence of the ionization energy on the atomic number determines the periodic law of chemical elements, which is assumed to be ...

World's first video recording of a space-time crystal

Periodic pattern consisting of magnons is formed at room temperature

10-Feb-2021

A German-Polish research team has succeeded in creating a micrometer-sized space-time crystal consisting of magnons at room temperature. With the help of the scanning transmission X-ray microscope MAXYMUS at Bessy II at Helmholtz Zentrum Berlin, they were able to film the recurring periodic ...

Two-phase material with surprising properties

10-Feb-2021

Microstructure and macroscopic electro-mechanical properties are closely coupled in so-called ferroelectric polymers. An explanation for the high temperature dependence of this coupling has now been found at TU Wien. In certain materials, electrical and mechanical effects are closely linked: for ...
